Hello, we have the intermittent RDP connection issue at work (I'm an IT support agent in my company). Some colleagues and myself too had this issue and the only solution I've found to resolve it was to uninstall two updates.
These two are the bad guys:
-
KB5049622
-
KB5050094
I had also to suspend Windows Updates due to the automatic reinstall and suddently return of the updates and the issue along. Hope this workaround could help.
PS: If you can't find in the uninstallable list is beacause you have to uninstall other updates first.
Once rebooted the issue is gone.
Edit: since many of my colleagues had these issues after I posted the answer, and I can't stop so many employees from working, I told my users to use the RDP app from Microsoft Store and it works fine even on fully updated clients. I'm pretty sure there's something that's preventing mstsc.exe or its dependencies from working properly. I've seen this solution on another thread, didn't even knew there were an RDP app from MSstore.
